Summary Proceedings of a Wind Shear Workshop

A number of recent program results and current issues were addressed: the data collection phase of the highly successful Joint Airport Weather Study (JAWS) Project and the NASA-B5f7B Gust Gradient Program, the use of these data for flight crew training through educational programs (e.g., films) and with manned flight training simulators, methods for post-accident determination of wind conditions from flight data recorders, the microburst wind shear phenomenon which was positively measured and described the ring vortex as a possible generating mechanism, the optimum flight procedure for use during an unexpected wind shear encounter, evaluation of the low-level wind shear alert system (LLWSAS), and assessment of the demonstrated and viable application of Doppler radar as an operational wind shear warning and detection system

A comparison of cultural ecosystem service survey methods within South England

AbstractAcross all societies, humans depend on goods received from nature, termed ecosystem services. However, cultural ecosystem services (CES), the non-material benefits people obtain from ecosystems, are often overlooked in land-use decision making due to their intangible nature. This study aimed to evaluate three possible survey methods for site-based CES data collection; language-based supervised surveys (in which interviewers conduct surveys in real-time, recording verbal responses), language-based unsupervised surveys (respondents complete written surveys without an interviewer), and image-based unsupervised surveys (respondents complete surveys via image selection without an interviewer). Language-based supervised surveys were found to be more efficient in collecting CES data than language-/image-based unsupervised surveys, with a mean completion rate over 1.5-fold greater than either unsupervised survey; furthermore, survey completion was over twice as fast, and less than a sixth of the monetary cost per respondent compared to unsupervised surveys. The site-based assessment developed in this study provides robust data, and is shown to provide rapid and useful feedback to land-use decision makers. We recommend that rapid, site-based assessment methods are utilised to collect the information required to support CES-related decision making

STEPS - an approach for human mobility modeling

In this paper we introduce Spatio-TEmporal Parametric Stepping (STEPS) - a simple parametric mobility model which can cover a large spectrum of human mobility patterns. STEPS makes abstraction of spatio-temporal preferences in human mobility by using a power law to rule the nodes movement. Nodes in STEPS have preferential attachment to favorite locations where they spend most of their time. Via simulations, we show that STEPS is able, not only to express the peer to peer properties such as inter-ontact/contact time and to reflect accurately realistic routing performance, but also to express the structural properties of the underlying interaction graph such as small-world phenomenon. Moreover, STEPS is easy to implement, exible to configure and also theoretically tractable

Follow-up of bone lesions in an experimental multiple myeloma mouse model: description of an in vivo technique using radiography dedicated for mammography.

The evolution of bone lesions in transplantable C57BL/KaLwRjj 5T mouse myeloma (MM) has been followed in vivo. Mice were anaesthetised and a radiograph of the pelvis and hind legs was performed by a radiograph dedicated for mammography. This is the first description of an in vivo technique under experimental conditions whereby the development of bone lesions owing to the MM growth was demonstrated

Efficacy of Online Training for Improving Camp Staff Competency

Preparing competent staff is a critical issue within the camp community. This quasi-experimental study examined the effectiveness of an online course for improving staff competency in camp healthcare practices among college-aged camp staff and a comparison group (N = 55). We hypothesized that working in camp would increase competency test scores due to opportunities for staff to experientially apply knowledge learned online. Hierarchical linear modeling was used to analyse the cross-level effects of a between-individuals factor (assignment to experimental or comparison group) and within-individual effects of time (pre-test, post-test #1, and post-test #2) on online course test scores. At post-test #2, the difference in average test scores between groups was ~30 points, with the treatment group scoring lower on average than the comparison group. Factors that may have influenced these findings are explored, including fatigue and the limited durability of online learning. Recommendations for research and practice are discussed

Exploring adolescents’ experiences of talking about race, ethnicity, and culture during Dialectical Behaviour Therapy (DBT): A qualitative study using thematic analysis

Background: Although anti-racist adaptations to Dialectical Behaviour Therapy (DBT) are emerging, little qualitative research exists exploring adolescents’ perspectives on therapists’ approach, cultural competency and humility regarding ethnicity, race, and culture (ERC) within DBT. This study explored diverse adolescents’ experiences of talking about ERC during all aspects of DBT treatment. Methods: Ten adolescents from diverse ERC backgrounds who attended DBT at a National and Specialist Child and Adolescent Mental Health Service (UK) completed semi-structured individual interviews that were transcribed verbatim and analysed using reflexive thematic analysis, adopting a critical realist approach. Results: Five overarching themes were developed from the data. Theme one captures the power for explicit ERC-related conversations to facilitate change, as they are frequently overlooked in therapy. Theme two discusses factors that facilitate or inhibit ERC-related discussions. Theme three captures the difficult “double bind” that adolescents find themselves in: not wanting to be a spokesperson for ERC issues whilst hoping for their therapist to facilitate/model ERC-related discussions. Theme four explores how adolescents navigated their identity in relation to ERC, their wider systemic context, and experiences of ERC-related trauma. Theme five explored therapeutic alliance, and how therapists might encourage DBT skills use with greater ERC sensitivity, emphasising validation. Conclusions: Using a bottom-up approach, we show a clear mandate from diverse adolescents for (White) clinicians to proactively create the space and safety required for ERC-related discussions. We emphasise the importance of anti-racist praxis including cultural humility, multi-cultural competencies, and validation of ERC-related difficult experiences within a wider systemic context
